I knew a bloke that lived in one of these; his wife threatened to divorce him if he didn't stop wearing it to bed. Just so comfortable! 100% cotton 12oz washed gravel canvas and fully cotton lined, so it will soak up sweat like it's going out of fashion, we added the built-in leather hatband and stitched the brim then placed a couple of large mesh eyelets to each side of the crown. Brim width- 2.1/2inch. Crown height- 3.1/4inch.
